I wish that people who reviewed devices with handwriting support would include some pictures showing math writing. Throw in an electronics schematic diagram or two, also. I want to know how well the thing works as a STEM writing scratchpad. If it can handle math and electronics reasonably well, that should be sufficient for most STEM.

Same here. I asked about exactly that a few months ago: https://news.ycombinator.com/item?id=15544996 Math writing needs a much higher resolution than ordinary text. For example if you are writing 2^2^2 the last 2 is really small. You also need a larger surface area so that you can draw diagrams and layout your calculations exactly as you want. I haven't tried ReMarkable myself, but from what I've heard, for math it…

I've been reasonably happy with my Surface Pro 4 for math, using OneNote. I do occasionally zoom in when writing something with more than one level of superscript or subscript, but it is responsive enough that zooming in or out is not overly annoying.

I'd be happier with a lighter device, though.

is there any way to tell it to use your cloud service instead of theirs ? In other words, what good is a custom reimplementation of it if you can't make it point at them without dns hacking?

Yes, you can SSH into the device and change a config file. This is a hacker's dream indeed.

How fast is the data transfer?

Do you think one could hack it into a "screen" by streaming a black-and-white image data from a computer to it?

So the connected computer would do all the heavy lifting related to rendering, compress the result to something that is really easy to decompress, send it over, and tablet would just decompress a bitmap and blit it to the screen?

They had a variety of pretty big engineering challenges to solve: getting the form factor right, making sure your hand didn't interfere with the screen while using it, getting the pen-and-paper feel right, and getting the e-ink refresh rate down to where you could draw and write on it and have it feel natural. I'm fine with them choosing to solve those challenges instead of supporting USB mass storage.

...and designing, developing, and supporting your own custom application and its associated protocol isn't an "engineering challenge"? USB mass storage requires exposing a block device with a filesystem, which is error-prone and complex. The point is, USBMS is a solved problem. My MP3/MP4 players, my Android phone, my satnav, even my soldering iron [1] can do it. The Linux kernel, which reMarkable uses, already inclu…

Yes, exposing a block device over USBMS is a solved problem.

Exposing files from a device's internal storage (which is ext4 in this case) over USBMS is very much not a solved issue. You'd have to copy the files back and forth or write a driver which emulates a FAT filesystem.

The alternative would be to use FAT internally and expose that block device, risking corruption (you have no control over what is done to your poor filesystem).

None of my Android phones can do that. In fact, Android used to expose the raw device in earlier releases and stopped doing it because it was too unreliable and the UX was bad since the filesystem had to be unmounted.

I guess if this device is targeted only at power users then rsync support is great. If they're hoping to make this a mass market device then they probably need something more user friendly.

Of course, but they are not mutually exclusive, you can offer both.

They do

Haven't tried, but you're either limited by USB2.0 or the wifi chip.

Given the low refresh rate of the panel, something like that should work just fine. Pretty sure I saw a YouTube video by someone who hacked it together using periodic screenshots.

This sounds really cool! Does this project have a name?

The Papertop. (It's a working title.)

Have you written any kind of blog or documentation about the build? I've been interested in a mini-laptop e-ink solution for a while. I think that most of the coding I do takes very little resources and is primarily just talking to the cloud or other servers. No reason to lug around a bunch of resources I don't need, right?

I haven't, and I'm disappointed to see that the display I used is now discontinued. That will push me to use a more effective one in the next iteration, which I'll write up.

I would buy this immediately if the screen were bigger. At least legal sized. (Am a musician, and our normal paper sizes in Orchestra are 9x12 or 10x12 inches.)

I agree that shrinking sheet music is a bit painful. But it does have in built page cropping, which I use a lot to fit A4 pages onto it.

I want the opposite. No cloud dependencies. Always-connected is a plague on modern computing that has ruined the experience for anyone with slow computers and/or unreliable networks. If you proposed a 3MB web page with 300ms API calls for every action and called that a replacement for an app for anyone with an unreliable/heavily metered connection you would be laughed out of the room. Yet that's the status quo of 'mo…

The Sony DPT-RP1 is a large e-ink reading device that works offline, but it's not available in Europe, just Japan and US. And of course they're getting some poor reviews for not having some bullshit cloud sync. Edit: I've heard Sony takes some privacy liberties with their EULA, so check that and maybe block their desktop app from connecting to the internet.

As of a few years ago the DPT-RP1 isn't even available in the US anymore, only Japan.
